Keep those Records
Most clients I meet don’t realize that you must keep your books and records for a minimum of six years. This includes both personal and business. Your records are used to determine your entitlements and tax obligations.
In order to destroy records, either paper or electronic, earlier than the required time, you must get written permission from the Canada Revenue Agency (CRA). You do so by applying in writing to the tax services office and providing a reason for your request. They will then determine if you are eligible or ineligible for your request.
